Actually, people have already tried to serialize PHP5 COM objects and hit a segfault :-)
It should be reasonably simple to serialize COM objects (there are a bunch of IPersistXXX interfaces we could use); the limitation right now is that our internals don't provide a sane way to implement it.
I can probably whip up a serialization interface over the weekend; it would work a bit like the iterators stuff - driven by a C interface that could wrap a userspace implementation if desired (although I'd be more interested in the internals here).
Sounds fine to me.
